This problem has been going on for more than a year now i have searched countless sites and forums i have tried a million different things but no solution could be found.
the problem is that whenever have crossfire enabled and i run a game with crossfire(i am aware that crossfire does not activate in borderless or windowed) it freezes my whole pc and there is nothing to get out of it, everything just freezes cursor, keyboard input, music, browser, windows EVERYTHING no exception all i can do is force shutdown my pc with the power button.
Ihave no clue what is the problem here are some things i tried:
I tested every individual stick of memory.
I swapped the gpu's no difference.
I tested both gpu's separately the work fine only in crossfire do they give problems.
I checked the power supply
I under clocked both cards(i also tested with 100% fan speed they stayed a cool 60 C)
I under clocked my cpu(and overclocked) no idea how that would affect it maybe drivers ¿?.
I did a vram test(all okay no errors)
I did a normal stress test on both gpu's and my cpu at the same time(ran fine)
I did opencl benchmark using all gpu's and cpu's(ran fine)
I switched to multiple different clean installs of windows 8, 8.1,10, and now i have 10 Insider.(no difference)
I disabled ULPS
I reset the registry edit i did (scroll further)
I googled for days (yet no similar problems with solution)
2x sapphire dual x 285 in crossfire
asrock 970 Extreme r2.0 (latest bios)
60 gig kingston ssd(windows 10 pro insider)
2 TB seagate barracuda(for steam and other programs)
16 GB Crucial ram
750 watt coolermaster powersupply
note: i did edit the register so that it would install programs on the D: drive by default instead of the C: drive
Please help me ;_;
